Today’s focus is on PHA, a bioplastic produced by certain bacteria from renewable resources such as sugars and vegetable oils.
Origin: natural, sustainable production
PHA (polyhydroxyalkanoate) is a biobased polymer produced by bacterial fermentation. Micro-organisms generate this material when they are fed with organic matter. This bioplastic is distinguished by its total biodegradability and compostability, including in marine environments. It is one of the few bioplastics capable of degrading under extreme conditions, making its end-of-life management particularly advantageous.
Its production is based on renewable resources, limiting dependence on fossil raw materials. In addition, the PHA manufacturing process can recover organic waste, making it an integral part of the circular economy.
Properties: performance and respect for the environment
PHA’s impressive technical properties make it an attractive choice for a wide range of applications:
- 100% biobased
- Biodegradable in different environments and industrially compostable
- Rigid
- Opaque
PHA is also biocompatible, which means it can be used without risk to human health, particularly in medical devices or food applications.
Applications: multiple, environmentally responsible uses
PHA is a versatile material that can be used in a variety of sectors:
- Horticulture / agriculture
- Rigid packaging: trays, pots, cans, etc.
- Consumer goods
- Aquarium / fish farming
A alternative for the future:
PHA is an alternative to petroleum-based plastics: it can be a solution for reducing our consumption of conventional plastics as its technical performance is comparable.
The future of PHA looks promising. With increasing investment in research and development, it is likely that this bioplastic will continue to gain in performance and accessibility.
